My 5 month old son had an ear bleed last night. We took him to the ER and a cbc showed he has an infection. They checked his ear and said the blood is only in the outer ear and here's nothing inside his ear. They said to have his ear drained which i was suppose to do tomorrow but now a drop of blood came out of his ear again and his ear is smelling bad. What is it? should i rush him to the er?
